$39.90 / BAG
MasterEmaco® T 545 HT formerly known as SET 45 is a one-component magnesium phosphate-based patching and repair mortar.
• Single component to just add water and mix • Reaches 2,000 psi compressive strength in 1 hour to rapidly return repairs to service • Takes rubber tire traffic in 45 minutes • Wide temperature use range from below freezing to hot weather exposures • Very low drying shrinkage for improved bond to concrete for repair and anchoring applications • Resistant to freeze/thaw cycles and deicing chemicals so it is usable in most environments • Air cure only, no wet curing compounds required • Coefficient of thermal expansion similar to Portland cement concrete for more permanent repairs • Higher sulfate resistance than conventional mortars
• Interior and exterior • Horizontal and formed vertical or overhead repairs • Applications requiring high early-strength gain • Structural concrete repairs • Partial and full-depth repairs • Cold temperature repairs • Grouting applications such as anchor bolts, rebar, dowel rods and precast applications
SURFACE PREPARATION 1.Concrete must be structurally sound and fully cured (28 days). 2.Saw cut the perimeter of the area being repaired into a square with a minimum depth of 1/2" (13 mm). 3.Refer to current ICRI Guideline no. 310.2R for surface prep requirements to permit proper bond. 4.Any surface carbonation in the repair area will inhibit chemical bonding. Apply a pH indicator to the prepared surface to test for carbonation. If carbonation is present, abrade surface to a depth that is not carbonated. MIXING 1.MasterEmaco T 545 must be mixed, placed, and finished within 10 minutes in normal temperatures (71° F [21° C]). Only mix quantities that can be placed in 10 minutes or less. 2.Do not deviate from the following sequence; it is important for reducing mixing time and producing a consistent mix. Use a minimum 1/2" slow-speed drill and mixing paddle or an appropriately sized forced-action mortar mixer. Do not mix by hand.
